NOTE
Trigger mode setting
This determines whether the trigger is accepted repeatedly after once
completing a measurement operation.
Pre-trigger setting
The pre-trigger setting can be used to record the waveform not only after but
also before triggering has occurred (memory recorder and RMS recorder
functions).
Trigger timing setting
The trigger timing setting refers to which of the start and stop events are
controlled by the trigger (recorder function).
Trigger marker
A trigger marker (
) appears at the trigger point (the point where a trigger
event occurred) on the waveform.
・If the trigger settings (trigger source parameters, pre-trigger) are changed
during recording, the measurement is restarted, using the new settings.
・If setting all of the trigger sources to OFF, the data is captured immediately
after measurement starts (free-run operation).
・During recording, the indication Waiting for trigger is shown on the display
until the trigger settings are met. During this interval, the level monitor is
also shown.
